Abstract (en)
[origin: EP1207663A2] An OFDM receiver includes a demodulation circuit (14), a differential detection circuit (19), and a first S/N ratio generation circuit (40). The demodulation circuit (14) receives an OFDM signal, which contains an information carrier (1), an additive-information transmission carrier (2), and a pilot signal (3), and converts the information carrier (1), the additive-information transmission carrier (2), and the pilot signal (3) into frequency-domain data. The differential detection circuit (19) conducts detection processing. The first S/N ratio generating circuit (40) generates an S/N ratio, based on a detection output provided from the differential detection circuit (19). The S/N ratio indicates the reception quality of the OFDM transmit signal. <IMAGE>
